Keywords and Parameters

Specify one or more objects using the "CHANGE BACKUP OFlistObjList" form of the command. Otherwise, CHANGE BACKUP operates on all backup sets, image copies, and proxy copies recorded in the repository.

If you are running CROSSCHECKBACKUP, then the command crosschecks BACKUP output that has status AVAILABLE or EXPIRED: backup sets (including backup pieces), proxy copies, and image copies. RMAN crosschecks all backups not marked UNAVAILABLE, even if they cannot be restored or if they are incremental backups whose parent full backup or copy no longer exists.

Specify one or more objects using the "CROSSCHECK BACKUPOFlistObjList" form of the command. Otherwise, RMAN crosschecks backups of the whole database.

Specify one or more objects using the "DELETE BACKUPOFlistObjList" form of the command. Otherwise, RMAN deletes backup sets of the whole database.

BACKUPSET

When followed by a list of primary keys: this is actually a case of the recordSpec syntax element in the syntax diagram for maintSpec. In such a case, the keys identify backupsets for use with the CHANGE, CROSSCHECK and DELETE commands. For more details, see "recordSpec" and "LIST Output" for an explanation of the column headings of the LIST output tables. Use the KEY column of the output to obtain the primary key usable in the CHANGE and DELETE commands.

Restricts the list of objects operated on to the object type specified in the listObjList clause. If you do not specify an object, then the command defaults to all copies. Note that CHANGECOPYOFDATABASE includes datafiles but not control files.

Allocates automatic channels for the specified device type only. This option is valid only if you have configured automatic channels and have not manually allocated channels. For example, if you configure automatic disk and tape channels and run CROSSCHECK...DEVICETYPEDISK, then RMAN allocates only disk channels.
